I recently changed the brakes on my 1986 300E. I have 4wheel disc. The brakes are made by mintex, but not the racing kind, so they shouldn't squeak. Not only do they squeak when I'm coming to a stop! Now, they are squeaking when I take-off, until I pick up speed then the squeaking goes away. Could this be that the rotors need to be cut? Keep in mind when I first changed the pads there was no problems at all!!
